Let's divide 537599 by 42
Let's see how many times 42 fits into 537599.

Going ahead to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 42

Let's proceed to step 2:
The number 42 fits into 53 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 53, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 42

Step 3:
If we divide 117 by 42, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 84 from 117 and we're left with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 42

Let's proceed to step 4:
42 can be fit into 335 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we take 294 away from 335, we end up with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 42

On to step 5:
42 can be fit into 419 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 1279.0
Subtracting 378 from 419 leaves us with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 42

On to step 6:
419 divided by 42 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 12799.0
The remainder is 41 after subtracting 378 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
42 can be fit into 410 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 12799.9
If we subtract 378 from 410, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 42 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 12799.97
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 12799.976
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 12799.9761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 12799.97619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12799.97619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 12799.9761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 12799.97619047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 12799.97619047, with a leftover of 2.6e-08.
